COMMENTARY/Medium Term--Capacity and Industry Structure

摘要

Table 6 shows that at the end of 2007 world primary aluminium smelter capacity was 41.30 million t/y at 262 identified plants. Of the world total 7.9m t/y was the older Soderberg anode technology, a proportion that is steadily falling as Soderberg smelters are closed or converted to prebaked anode technology. Table 7 lists all committed changes to primary smelter capacity. By 2012 these projects will add 9.53 million tonnes (net) to world capacity, of which 1.92m tonnes was scheduled to start up in 2008. Since the last a large smelter project by UC Rusal in Russia has been added, starting production in 2011.
